Description

Technical Field

[0001] This invention relates to the field of synthetic foam fire extinguishing agent production technology, and in particular to an environmentally friendly synthetic foam fire extinguishing agent production apparatus and its preparation process. Background Technology

[0002] In the industrial production of environmentally friendly synthetic foam fire extinguishing agents, traditional mixing equipment has significant limitations. First, to achieve premixing of different materials, multiple premixing kettles are often required, which are then transferred to the main reactor for final mixing. This process involves large equipment investment, high energy consumption, and the risk of cross-contamination.

[0003] Secondly, traditional mixers rely on external motors for operation, making continuous operation impossible during feeding intervals or circulation phases, thus affecting mixing efficiency and uniformity. More importantly, as a colloidal solution, the stability of synthetic foam fire extinguishing agents is highly dependent on the degree of homogenization of its components. Conventional mixing provides limited shear force, making it difficult to effectively break up colloids and aggregates, leading to product stratification and performance degradation during long-term storage. Therefore, the industry urgently needs a production device that integrates zoned premixing, high-efficiency driving, and online homogenization to achieve continuous, efficient, and stable production from feeding to output, ensuring the superior performance of the final product. We propose an environmentally friendly synthetic foam fire extinguishing agent production device and its preparation process. Summary of the Invention

The fixed plate is provided with mounting cavities on both sides, and the mounting cavities are provided with a rotating frame, a first support cylinder, a movable rod, a second support cylinder, and a locking block. The drive assembly includes two sets of fixed tubes, with a rotating cylinder rotatably mounted on the side of the fixed tubes. A fixed frame, a matching rod, and a fan blade block are provided on the inner side of the rotating cylinder. A stirring rod is fixedly mounted at equal intervals on the side of the rotating cylinder. The circulation assembly includes two sets of circulation pipes. A circulation pump and a one-way valve are provided on the side of the circulation pipes. An installation block, a movable block, and a fan blade are provided on the inner side of the circulation pipes. A second shear groove and a guide groove are provided on the side of the installation block, and a first shear groove is provided on the side of the movable block.

[0006] Furthermore, the fixed plate is fixedly installed inside the reactor, and the mating grooves are symmetrically opened on both sides of the fixed plate. The movable plate is movably engaged inside the mating grooves. The second groove and the first groove are staggered. The mating blocks are fixedly installed at equal intervals on the side of the movable plate. The rotating frame is rotatably installed through the wall of the mounting cavity. The first support cylinder is fixedly connected between the rotating frame and the side of the movable plate.

[0007] Furthermore, the movable rod is disposed through the center of the movable plate and the movable plate is slidably fitted to the side of the movable rod with splines. The second support cylinder is fixedly connected between the movable rod and the side of the movable plate and is movably sleeved on the side of the movable rod. The movable rod and the second support cylinder are disposed inside the first support cylinder. The locking block is fixedly installed on the side of the movable rod away from the movable plate. A connecting groove is provided between the walls of the mounting cavity. A connecting pipe is provided on the bottom side of the reactor and passes through the reactor and the fixed plate to the inside of the connecting groove.

[0008] Furthermore, the two sets of fixed pipes are fixedly installed on both sides of the reactor. The first and second material pipes are fixedly installed through the side of one set of fixed pipes, and the third and fourth material pipes are fixedly installed through the side of the other set of fixed pipes. A discharge chute is provided on the side of the rotating cylinder.

[0009] Furthermore, the stirring rod is attached to the outside of the fixed tube, the fixed frame is fixedly installed at equal intervals on the inside of the rotating cylinder, the splines at both ends of the mating rod are snapped into the inside of the fixed frame, the fan blade blocks are fixedly installed at equal intervals on the side of the mating rod, and a slot is provided at the center of the side of the rotating cylinder.

[0010] Furthermore, the two sets of circulation pipes are fixedly connected between the lower side of the reactor and the side of the fixed pipe, and a one-way valve is fixedly installed inside the circulation pipe.

[0011] Furthermore, the mounting block is fixedly installed inside the circulation pipe, and a flow guide cavity is provided on the side of the mounting block. The movable block is rotatably installed inside the mounting block, and the fan blade rod is fixedly installed inside the movable block. The first shear groove is equidistantly opened on the side of the movable block, and the second shear groove is equidistantly opened on the side of the mounting block corresponding to the position of the first shear groove. The flow guide groove is equidistantly opened on the side of the mounting block.

[0012] A preparation process for an environmentally friendly synthetic foam fire extinguishing agent production device includes the following steps: Step 1: Divide the interior of the reactor into two spaces; Step 2: Deliver the corresponding base liquid, polymer solution, solvent, and active solution to the spaces on both sides of the reactor, respectively; Step 2.1: The base liquid and polymer solution are premixed and stirred in the left side area; Step 2.2: The solvent and active solution are premixed and stirred in the left side area; Step 2.3: After the premixed materials are conveyed, but before the mixing is complete, solution circulation and shear homogenization are performed. Step 3: Connect the inside of the reaction vessel to unify the mixture, and then mix the two premixed solutions together; Step 4: While stirring, the solution is circulated and supplied, and shearing and homogenization are performed simultaneously. This, combined with the two sets of premixed solutions, accelerates the mixing process.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. The present invention.

[0014] 2. The present invention uses an isolation component consisting of a fixed plate, a movable plate, and a first support cylinder to achieve physical partitioning within a single reactor, thereby enabling the simultaneous independent preparation of two premixed liquids. This avoids the cumbersome and contamination risks associated with traditional multi-reactor operations. When gas pressure is introduced to detach the movable plate, the premixing zones are connected. The movable plate rotates under the drive of the drive component, and the mating block on it becomes a stirring blade, which greatly accelerates the mixing of the two premixed liquids.

[0015] 3. This invention, by setting up a drive component, converts the kinetic energy of the fluid into mechanical energy. When the material is input, the flowing liquid impacts the fan blades, and through the connecting rod and the fixed frame, it drives the entire rotating cylinder to rotate, thereby driving the stirring rod to achieve stirring. During the feeding interval, the circulation component maintains the fluid circulation, thus providing continuous power to the self-driven stirring system, ensuring that the mixing process is uninterrupted and effectively reducing the energy consumption of the equipment.

[0016] 4. This invention sets up a circulation component, in which the mounting block and the movable block in the circulation component constitute a high-speed shear homogenizer. The circulating liquid drives the fan blade to rotate the movable block at high speed, forcing the liquid to pass through the tiny gap between the first shear groove on it and the stationary second shear groove on the mounting block. Due to the high-speed relative motion between the two, the liquid is subjected to extremely strong shearing, tearing and impact at this point, thereby achieving efficient online homogenization. In addition, the liquid circulation can also accelerate the liquid mixing effect.

[0017] 5. The linkage design between the isolation component and the drive component of this invention allows the locking block at the end of the movable rod to automatically find and engage with the slot of the rotating cylinder under the elastic support of the second support cylinder, realizing the automatic disengagement of the movable plate and the rotating cylinder. This process does not require additional sensors and actuators, and the mechanical structure completes it automatically, ensuring the smooth, reliable and automated switching of the equipment from zoned premixing to overall mixing mode.

[0020] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figure 1 and Figure 2As shown, an environmentally friendly synthetic foam fire extinguishing agent production device includes a reactor 1, with a support 11 symmetrically fixedly fitted on the side of the reactor 1. An isolation component 2 is provided at the center of the reactor 1. A drive component 3 and a circulation component 4 are provided on both sides of the reactor 1. The isolation component 2 is used to partition and isolate the interior of the reactor 1 and can be used in conjunction with subsequent stirring. The drive component 3 uses fluid power to automatically stir, and the circulation component 4 realizes continuous circulation of materials to maintain stirring power and complete shear homogenization.

[0022] like Figures 2 to 5As shown, the isolation assembly 2 includes a fixed plate 21, which is fixedly installed inside the reactor 1. The fixed plate 21 is a circular plate. A first slot 211, which is fan-shaped, is equidistantly arranged in a circumferential array on the side of the fixed plate 21. A mating slot 212, which is annular, is symmetrically arranged on both sides of the fixed plate 21. A movable plate 22 is mirror-arranged on both sides of the fixed plate 21 and is movably engaged within the mating slot 212. The movable plate 22 is a circular plate with one side open. A second slot 221, which is equidistantly arranged in a circumferential array on the side of the movable plate 22, is equidistantly arranged in a circumferential array. By default, the second slot 221 and the first slot 211 are staggered. The second slot 221 is... A fan-shaped groove is provided, and mating blocks 222 are fixedly installed in a circumferential array at equal intervals on the side of the movable plate 22. The mating blocks 222 are rectangular blocks. An installation cavity 23 is provided at the center of both sides of the fixed plate 21. The installation cavity 23 is a circular cavity. A rotating frame 231 is rotatably mounted through the wall of the installation cavity 23. The rotating frame 231 is a circular ring frame with a "Z"-shaped cross-section. A first support cylinder 24 is fixedly connected between the rotating frame 231 and the side of the movable plate 22. The first support cylinder 24 is a corrugated cylinder of elastic material. A movable rod 25 is provided through the center of the movable plate 22, and the movable plate 22 is splinedly slidably fitted to the side of the movable rod 25. The movable rod 25 is a convex-shaped splined rod. A second support cylinder 251 is fixedly connected to the movable rod 25 and movably sleeved on the side of the movable rod 25. The movable rod 25 and the second support cylinder 251 are located inside the first support cylinder 24. The second support cylinder 251 is a corrugated cylinder made of elastic material. A locking block 26 is fixedly installed on the side of the movable rod 25 away from the movable plate 22. The locking block 26 is a regular hexagonal block. A connecting groove 27 penetrating the movable plate 22 is opened between the walls of the mounting cavity 23. A connecting pipe 28 is provided on the bottom side of the reactor 1 and penetrates the reactor 1 and the fixed plate 21 to the inside of the connecting groove 27. The connecting pipe 28 is externally connected to the compressor module. Specifically, by default, the movable plate 22 is held in place by the elastic tension of the first support cylinder 24. The movable plate 22 is attached to the inside of the mating groove 212, so that the movable plate 22 fits against the side of the fixed plate 21. At this time, the second slot 221 and the first slot 211 are staggered, and the fixed plate 21 and the movable plate 22 can cooperate to isolate the inside of the reactor 1. Subsequently, pressurized gas is supplied through the connecting pipe 28. The gas is discharged from the connecting groove 27 into the mounting cavity 23. The pressure can push the movable plate 22 out of the mating groove 212. At this time, the inside of the reactor 1 can be connected through the second slot 221 and the first slot 211. In addition, the locking block 26 can be connected to the subsequent components, so that the movable plate 22 can rotate synchronously to assist in stirring inside the reactor 1, so that the premixed liquid on both sides of the reactor 1 can be more quickly mixed.

[0023] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the drive assembly 3 includes two sets of fixed tubes 31, which are mirror images of each other and fixedly installed on both sides of the reactor 1. Each fixed tube 31 is a cylindrical tube with one side open. A first feed pipe 311 and a second feed pipe 312 are fixedly installed through one side of the fixed tube 31, and a third feed pipe 313 and a fourth feed pipe 314 are fixedly installed through the other side of the fixed tube 31. Flow meters are installed on the sides of the first feed pipe 311, the second feed pipe 312, the third feed pipe 313, and the fourth feed pipe 314. A rotating cylinder 32 is rotatably installed on the side of the two sets of fixed tubes 31 that are close to each other. The rotating cylinder 32 is a convex tube with one side open. A cylindrical rod is provided, and discharge slots 321 are provided in a circumferential array at equal intervals on the side of the rotating cylinder 32. Stirring rods 322 are fixedly installed in a circumferential array at equal intervals on the side of the rotating cylinder 32, and the stirring rods 322 are attached to the outside of the fixed tube 31. The stirring rods 322 are "E"-shaped rods. Two sets of fixing frames 33 are fixedly installed at equal intervals on the inner side of the rotating cylinder 32. The fixing frames 33 are snowflake-shaped ring frames. A mating rod 34 is provided between the two sets of fixing frames 33, and the two ends of the mating rod 34 are splined and engaged with the inner side of the fixing frame 33. The mating rod 34 is a cylindrical rod with a cross-shaped cross section. Stirring rods 34 are fixedly installed in a circumferential array at equal intervals on the side of the mating rod 34. Equipped with fan blade blocks 35, a slot 36 is provided at the center of the side of the rotating cylinder 32 near the movable plate 22. The slot 36 is a regular hexagonal groove. Specifically, various solution materials can be input through the first material pipe 311, the second material pipe 312, the third material pipe 313, and the fourth material pipe 314. After the solution material flows from the fixed pipe 31 to the rotating cylinder 32, it can be discharged from the discharge trough 321 into the interior of the reactor 1. Simultaneously, the fan blade blocks 35 are impacted by the solution material, and the fan blade blocks 35 drive the cooperating rod 34 to rotate, which in turn drives the rotating cylinder 32 to rotate. When the rotating cylinder 32 rotates, it drives the fixed frame 33 to move inside the reactor 1. The solution material is stirred, which is driven by water flow. Additionally, the subsequent locking block 26 engages inside the locking groove 36. The rotation of the rotating cylinder 32 drives the movable plate 22 to rotate synchronously. If the locking block 26 does not align with the locking groove 36, it will press against the side of the rotating cylinder 32, causing the movable rod 25 to slide under pressure. The second support cylinder 251 deforms in response until the locking block 26 aligns with the locking groove 36. Under the elastic support of the second support cylinder 251, the locking block 26 is then locked into the position inside the locking groove 36. When the movable plate 22 rotates, its rotation is constrained by the cooperation of the first support cylinder 24 and the rotating frame 231.

[0024] like Figure 3 , Figure 7 and Figure 8As shown, the circulation assembly 4 includes two sets of circulation pipes 41, which are fixedly connected between the lower side of the reactor 1 and the side of the fixed pipe 31. A circulation pump 42 is installed on the side of the circulation pipe 41 to pump the solution inside the reactor 1 into the fixed pipe 31. A one-way valve 43 is fixedly installed inside the circulation pipe 41. An installation block 44 is fixedly installed on the inner side of the circulation pipe 41. The installation block 44 is an I-shaped cylindrical block. A guide cavity 441 is opened on the side of the installation block 44 near the circulation pump 42. 41 is a cylindrical cavity. Inside the guide cavity 441, a movable block 45 is provided and rotatably mounted on the side of the mounting block 44. The movable block 45 is a cylindrical block with one side hollowed out. A fan blade rod 46 is fixedly mounted on the inner side of the movable block 45. The fan blade rod 46 is a "T"-shaped cylindrical rod with fan blades mounted on the side. A first shearing groove 47 is equidistantly arranged in a circular array on the side of the movable block 45. A second shearing groove 48 is equidistantly arranged in a circular array on the side of the mounting block 44 corresponding to the position of the first shearing groove 47, penetrating through it. The first shear groove 47 and the second shear groove 48 are rectangular grooves, with the second shear groove 48 being wider than the first shear groove 47. A guide groove 442 is provided at equal intervals on the side of the mounting block 44 corresponding to the position of the second shear groove 48, penetrating through it. Specifically, after the solution inside the reactor 1 is transported, the circulating pump 42 extracts the solution from the middle position inside the reactor 1, circulating it through the circulating pipe 41 to the fixed pipe 31. The one-way valve 43 ensures that the solution can only flow in one direction. During the flow, the solution enters the inner position of the movable block 45 through the guide cavity 441. The solution impacts the fan blade 46, causing it to rotate, which in turn drives the movable block 45 to rotate synchronously. The solution is forced through the tiny gap between the first shear groove 47 on the rotating movable block 45 and the second shear groove 48 on the stationary mounting block 44. Due to the high-speed relative motion between the two, the solution is subjected to strong shearing action at this point, thus achieving homogenization. Simultaneously, after flowing, the solution can flow from the fixed pipe 31 to the rotating cylinder 32 and be discharged from the discharge trough 321, achieving solution circulation.

[0025] Working principle: In use: the dual-zone solution is premixed, and the movable plate 22 is elastically pulled by the first support cylinder 24 and is movably engaged inside the mating groove 212. At this time, the positions of the second groove 221 and the first groove 211 are staggered, and the fixed plate 21 and the movable plate 22 isolate and partition the inside of the reactor 1. The left side region is simultaneously supplied with base liquid (deionized water) and polymer solution (such as xanthan gum) through the first feed pipe 311 and the second feed pipe 312, while the right side region is supplied with solvent (ethylene glycol butyl ether) and active solution (such as hydrocarbon surfactants and environmentally friendly fluorocarbon surfactants) through the third feed pipe 313 and the fourth feed pipe 314. After the solution flows from the fixed pipe 31 to the rotating cylinder 32, it can be discharged into the reactor 1 from the discharge trough 321. At the same time, the solution drives the fan blade block 35 to rotate the matching rod 34. The matching rod 34 drives the rotating cylinder 32 to rotate through the fixed frame 33. The rotating cylinder 32 drives the stirring rod 322 to perform premixing of the solutions. Meanwhile, the stirring of the fan blade block 35 can also enhance the mixing effect of base liquid, polymer solution and solvent and active solution. After the above solution is transported, the material is stopped and the premixing is not completed. At this time, the circulation pump 42 works to pump the liquid at the bottom of the reactor 1, so that the liquid is pumped back to the fixed pipe 31. In this way, the stirring rod 322 can still be driven to rotate and continue stirring by the liquid flow. When the liquid flows inside the circulation pipe 41, the liquid impacts the fan blade 46, causing the movable block 45 to rotate. After passing through the first shear groove 47 and the second shear groove 48, the liquid flows out from the movable plate 22 of the circulation component 4. The rotating movable block 45 can make the first shear groove 47 and the second shear groove 48 shear and homogenize the liquid.

[0026] After the single-zone solution is fully mixed and premixed, pressurized gas is immediately supplied through the connecting pipe 28. The gas is discharged from the connecting groove 27 into the installation cavity 23. The gas pressure pushes the movable plate 22 away from the mating groove 212, and the first support cylinder 24 is squeezed and stretched accordingly. During this process, when the movable plate 22 moves away from the side of the fixed plate 21, the locking block 26 will press against the side of the rotating cylinder 32. The movable rod 25 and the second support cylinder 251 cooperate to provide elastic support for the locking block 26 until the locking block 26 is completely aligned with the locking groove 36. The locking block 26 can then be elastically locked into the locking groove 36, and the rotating cylinder 32 can drive the movable plate 22 to rotate accordingly. At this time, the liquid can complete the connection inside the reactor 1 through the first slot 211 and the second slot 221. In addition, the rotation of the mating block 222 driven by the movable plate 22 can also enhance the stirring effect. At the same time, the circulation pump 42 works to draw liquid from the middle area inside the reactor 1, which can accelerate the mixing of the premixed solutions on both sides of the reactor 1. Meanwhile, when the solution circulates from the circulation pipe 41, it is sheared and homogenized by the first shear groove 47 and the second shear groove 48, which can make the rotating cylinder 32 continuously driven to drive the stirring rod 322 to rotate. The two sets of premixed solutions can also form a circulation to accelerate mixing, resulting in a better mixing effect of the finished solution.

[0027] A preparation process for an environmentally friendly synthetic foam fire extinguishing agent production device, such as... Figure 9 As shown, it includes the following steps: Step 1: Divide the interior of the reactor into two spaces; Step 2: Deliver the corresponding base liquid, polymer solution, solvent, and active solution to the spaces on both sides of the reactor, respectively; Step 2.1: The base liquid and polymer solution are premixed and stirred in the left side area; Step 2.2: The solvent and active solution are premixed and stirred in the left side area; Step 2.3: After the premixed materials are conveyed, but before the mixing is complete, solution circulation and shear homogenization are performed. Step 3: Connect the inside of the reaction vessel to unify the mixture, and then mix the two premixed solutions together; Step 4: While stirring, the solution is circulated and supplied, and shearing and homogenization are performed simultaneously. This, combined with the two sets of premixed solutions, accelerates the mixing process.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
